The remarkable 2015 Dodge Charger SRT Hellcat is the fastest and most powerful sedan around the world. In order to strike with even more staggering virtues, the car boasts fuel-economy statistics as impressive as its performance characteristics. Now the Dodge Charger SRT Hellcat has received an EPA fuel economy rating of 13 miles per gallon in the city and a 22 miles per gallon on the highway. Maybe 13 miles per gallon in the city is not such a stunning figure, but getting more than 20 miles per gallon on the highway is, in fact, quite phenomenal. Under the hoot there is an always-craving 6.2-liter supercharged V-8 engine which boosts the impressive 707 HP. If we had to describe the effect of this significant power, it would be something similar to a quick-winning roulette game on supercasino which is able to make your jaw drop. What is more, the 2015 SRT Hellcat has recorded an 11-second quarter-mile on street tires, which is certified by the National Hot Rod Association (NHRA). The car sprints from 0-100 mph in less than 13 seconds with a top speed of 204 mph. This is precisely what makes the vehicle the quickest sedan ever. Something that is of central importance to the car’s performance is the new TorqueFlite eight-speed automatic transmission. It generates 30 percent more peak engine-torque volume than any eight-speed automatic transmissions which have been offered in the past by Chrysler Group. The price of the world's only four-door muscle car is estimated at $63,995, including a $1,700 gas-guzzler tax. Source: Dodge
